Purpose: This paper briefly describes the data acquisition software of the updated SAXS/XRD/XAFS station at beamline 1W2B of Beijing Synchrotron Radiation Facility (BSRF), so as to facilitate users to choose a more suitable experimental mode and configure the data acquisition parameters of the combined measurements. Methods: Based on the equipment control and data acquisition network system, routine or anomalous small-angle X-ray scattering (SAXS, ASAXS) data, routine or anomalous X-ray diffraction (XRD, AXRD) data, as well as X-ray absorption fine structure (XAFS) data can be simultaneously or separately acquired without the need for mechanical switching. Multiple experimental modes, including routine XAFS measurements, routine SAXS/XRD combined measurements, quick or slow SAXS/XRD/XAFS combined measurements, as well as ASAXS/AXRD combined measurements are available. Results: With the BSRF upgrade, the updated experimental station at beamline 1W2B focuses more on SAXS/XRD/XAFS combined technique and anomalous X-ray scattering technique. The updated station has an intrinsic seconds-level time resolution, and a variety of experimental modes are available. Combined with in situ sample environment system, atomic local structure, nanoscale structure, long-range ordered structure, and element-specific distribution can be detected simultaneously under in situ conditions. Choosing the appropriate data acquisition software, correctly configuring the data acquisition parameters, and performing necessary data preprocessing are the prerequisites for successfully obtaining effective combined data.
